Fort Washington, Pennsylvania

Fort Washington is a census-designated place and suburb of Philadelphia in Montgomery County, Pennsylvania. Prior to the American Revolutionary War, the area was settled by many German immigrants. During the Philadelphia campaign of the Revolutionary War, George Washington and the Continental Army encamped there after the 4 October 1777 defeat at the Battle of Germantown, and immediately prior to their march to Valley Forge. From 5 to 8 December 1777, the Battle of White Marsh was fought there. The town was named for the American defenses and encampment established in the area in 1777, and the town was the site of the horrific "Great Train Wreck of 1856", in which 59 people (mostly Catholic schoolchildren) were killed when two North Pennsylvania Railroad trains collided. On 1 January 1946, Fort Washington was incorporated into both Upper Dublin and Whitemarsh. In 2010, Fort Washington had a population of 5,446 people.
